Programmable 4–bit counter with synchronous reset in bare die form

Description
The 54HCT163 programmable synchronous 4-bit decade
and binary counter is fabricated using a 2.5μm 5V CMOS
process with the same high speed performance of LSTTL
combined with CMOS low power consumption. Clock
input is active on the rising edge. Both load (SPE) and
clear (MR) inputs are active low. Presetting is synchronous
on rising clock edge. Two enable inputs (TE and PE) and
ripple carry output (TC) are provided to enable easy
cascading of counters, facilitating simple implementation
of N-bit counters without use of external gates. Device
inputs directly accept LSTTL or CMOS. All inputs are
protected against ESD and excess voltage transients.

Features:
Output Drive Capability: 10 LSTTL Loads
Low Input Current: 1μA
TTL / CMOS compatible Input Levels
Outputs directly interface CMOS, NMOS and TTL
Operating Voltage Range: 4.5V to 5.5V
Function compatible with 54LS163
Full Military Temperature Range.
